Synchronizing Outlook on Two Computers

Last reviewed on February 7, 2014

There are many techniques for keeping your Outlook information on two different machines. However, Microsoft has not released a synchronization utility for Outlook.

Note that the methods on this page or sync utilities are not necessary if you have a Hotmail/Live account and use the Outlook Hotmail connector as it syncs messages, calendar and contacts between Outlook and online. Utilities are also not needed if you have an Exchange server account.

For simple “syncing” of email, choose an IMAP email account if your email provider supports it. If you use a POP3 account, leave mail on the server until the other computer has downloaded the messages and BCC yourself on sent messages. You can send appointments and contacts to yourself as needed, or use one of the methods below to copy non-mail items to your other computers.

Listed below are three methods which do not require third party tools, along with tools that will sync two Outlooks.

For tools you can use to sync between Exchange Public folders and mailboxes, see Synchronizing Exchange Mailboxes and Public Folders.

Synchronizing Outlook using Web Services has information on using Internet services to sync two copies of Outlook.

Built-in methods | PDA | Windows Briefcase
Other Tools | More Information

Built-in methods

These include:

  • For Exchange Server users, offline folders to replicate data from your mailbox and favorite Public Folders to a remote system
  • Copying all or part of your Personal Folders File (see Windows Briefcase below)



If you use a Palm device, PocketPC, other PDA, check to see whether your synchronization software allows you to synchronize the device with more than one computer. If so, you may be able to use the PDA as an intermediary to synchronize two computers:

Computer 1 <-> PDA <-> Computer 2

Good backups on both computers would be essential to ensure that you can always roll back to a previously synchronized set of data. See Synchronizing Microsoft Outlook with a PDA for tools.

Windows Briefcase

This solution comes from F.E. Froelich:

I think I have found a relatively painless way to share Microsoft Outlook between my laptop, which I travel with, and my desktop without having to connect the two computers together.

I created a directory for the two Outlook files Mailbox.pab and Mailbox.pst. I then copied the directory into My Briefcase. I then placed My Briefcase onto a disk. (I have a Zip drive on both computers, so I keep a Zip disk with nothing but My Briefcase on it for sharing files between my laptop and desktop.) I then deleted the Mailbox.pab and Mailbox.pst files from my laptop and copied the two files from My Briefcase into a directory on the laptop.

When I am ready to leave with the laptop, I put the My Briefcase Zip disk into the desktop and update the files, then put the same disk into my laptop and update. When I come back, I reverse the sequence. So far it seems to work.

As an aside, I have copied the entire My Documents directory into My Briefcase on the same Zip disk. Now all of my Word, Excel, Powerpoint, and Access files are kept up to date between the two computers. When I create a new file or subdirectory on one computer, it is automatically added to the other computer the next time I do an update. This approach is much more efficient than trying to make sure that I have placed all of the individual files that I need into My Briefcase. There is no better way to manage My Briefcase than with a Zip drive (unless you have a LAN).

(Editors note: If you don’t have a Zip drive, you can use a USB key instead.)

Note that the file names may differ on your machine. See Outlook & Exchange/Windows Messaging Backup and Dual-Boot for default names and locations.

Beginning with Windows 2000, Windows versions offer a feature for taking files offline, but by default, it excludes Personal Folders .pst files. However, you can edit the system policy that controls the file types so that .pst files can be included. See Error Message Files of This Type Cannot Be Made Available Offline.
